In the video below, two German lower league clubs – Kickers Offenbach and Viktoria Berlin – can be seen in action in a friendly game.
Everything is hunky dory until Offenbach’s Robin Scheu launched a (literally) gut wrenching kung fu kick on Berlin's Stephan Brehmer.
With the ball in the air, Scheu went in flying and planted a left kick straight into Brehmer's stomach. The foul's ridiculousness is reflected in the commentators' tempo, which goes from 0-100 as soon as Scheu connects. You wouldn't get a word of what they're saying, but it's clear how mad they are at the incident.
The kick was so bad it warranted an all-out brawl, and folks actually did start on the touchlines, but credit to them, they didn't let it escalate any further.
